Abstrakty
The paper presents results of georadar positioning of a set of subsurface conduits, together with an assessment of efficiency of their detection. The measurements on test fields were performed with the RAMAC/GPR georadar, produced in Sweden by the Mala GeoScience Company. Numerous radargrams were properly processed with an optimal filtering sequence, aimed at production of a readable image of the detected conduits. The results were assessed also from the efficiency point of view of the subsurface structure detection method. The phenomenon of signal polarization, which helps to distinguish metallic and plastic conduits, is also discussed. Elements of surveying and computational procedures, leading to completion of content of digital thematic maps by the georadar sensing integrated with GPS positioning, are also given.
